Application filed December 8, 1920. Serial No. 428,554.

To all 'IIIIOIN it may concern:

Be it known that I, ALFRED R. GIFFIN, a citizen of the United States,residing at Cleveland. in the county of ("uyahoga and State of Ohio,have invented certain new and useful Improvements in Oil Purifiers, ofwhich the following is a specification.

'lhis inventionlrelates to gasoline, paraffin, coal oil. and crude oilpurifiers, the principal object of which is the purification of suchoils as may be passed through it.

Another object of theinvention is to raise the actual s'pecific gravityof various oils, which are passed through it.

Another object of the invention is to proride a purifier which may beutilized and attached to any style of internal combustion engine.

Another object of the invention is to provide a purifier whicheliminates the deposit of carbon which is usually found on the internalparts of internal combustion engines.

Another object of the invention is to eliminate carburetor and sparkplug troubles. by removing such elements as carbon and other impuritiesin the fuel being used before said fuel reaches these specific parts ofthe engine.

Another object of the invention is to promote a general better runningcondition for the entire engine.

Another object of the invention is to provide a gas purifier or filter,which will auto-- matically deliver more thermal units of heat energy,from a specific quantity of fuel, thereby increasing mileage w enapplied to mobile engines or more actual horsepower when utilized forstationary engines,

Another object of the invention is to provide a purifier for internalcombustion engines which will reduce the actual fuel consumption.

Another object of the invention is to provide a purifier of gasproducing liquids, which is simple in construction, efiicient inoperation and one which can be manufactured and placed upon the marketat a minimum cost.

The invention also consists in certain other features of construction,to be hereinafter fully described, illustrated in the accompanyingdrawings, and specifically pointed out in the appended claim. v

In describing my invention in detail, reference will be had to theaccompanying the cover removed.

Referring to these drawings, 1 is a metal.

strap, one end of which is threaded and screwed into the cap 2 andsecurely locked in position by the lock ring or nut 3.

It will be noted that the strap 1 is a straight fiat piece of metal,which may be drilled and bent up to conform to theposition in which itis most desired to retain the purifier. The cap has an inner stem 18pro- 'vided with a shoulder 4 which acts as a retaining member for theupper screen. 13 (Figure 2) when cap 2 is screwed into closed positionand the butt end shoulder 5 on the stem acts as a retaining member forthe lower screen 12 Figure 2. 6 is a suitable gas proo'f gasket placedbetween the shoulder on the cover 2 and the upper edge of the bowl 7.

The bowl 7 forms the containing element for the whole. It will be notedthat the bowl element 7 has a bottom in the form of a specific parabola,which is so constructed that it forms an irregular ellipse with thelines taken by the parabola of the screen members 12 and 13 which isrequisite, and most necessary in the correct functioning of said membersas hereinafter described.

8 is the inlet port or pipe connection which constitutes the entrancepoint for the liquid fuel, said ort 8 being placed at a. specific angle,con orming to an imagine. central line drawn from the center of a ho ein said port or inlet 8 to the center of the parabola of the 'lowerscreen 12 and striking said screen at the contact point of shoulder 5when in position and locked against the center of screen 12.

9 is a plug which is screwed into the botton of the parabolic bowl 7said plug having a gas tight washer 1O placed between it and the bowl,said plug 9 having a hollow space 11 which forms-a. well or sedimentzone, into which the impurities settle and there stay, until said member9 is unscrewed and cleaned out.

12 is the lower parabolic screen which it will be noted in Figure 3is'composed of a screen fabric the mesh of which runs preferably aboutfourteen thousand' spaces to the square inch. 7

13 is the upper parabolic screen which runs about fifty-seven thousandspaces to the square inch or two hundred forty standard mesh, which meshis the approximate density of chamois skin leathers 14 is the outletport or pipe connectlon through which the liquid fuel passes into thecarburetor (not shown) after having passed through the screeningprocess.

15 and 16 are retaining shoulders upon which the screen members 12 and13 rest and to which they are securely locked, when the cap or lid 2 isscrewed into place, bring-' ing the contact pole 18 on lid into'contactand exerting downward pressure on the convex surface of the parabola; ofthe screens 12 and 13 by the shoulder membe 4 and 5 on pin 18 saiddownward pressure having a tendency to increase the outer diameter ofthe screens 12 and 13 and thereby securely locking said screens, againstand down upon the shoulders 15 and 1 It will be noted, upper screen 13has a hole 17 to allow for passage of pin 18 when placed in the lockedposition.

It is an established fact, that the screen 12 will stop normal particesof foreign matter from passing, and that the fine screen 13 will allowgasoline and liquid fuel of similar specific gravity to pass, but willnot allow water to pass.

It is also desired to be pointed out that the normal pressure on saidliquid fuels, will be approximately three (3) pounds to the square inch,or more in high pressure feed systems where even smaller mesh screensmay be utilized.

It may be noted that the container 7 ma v have additional screens,several inlets and outlets, etc. It may also be noted. that the plug andsediment well 9, may have greater length and also have a glass tubeinset thereto, to make said sediment visible if so desired. Theparabolic shape of the bowl 7 will allow the sediment to settle in thecenter or ical means for retaining said screens in position.

It will be'noted that the oil is introduced at an angle and inexplanation thereof will say that the oil, or current, or pressure isshot upward to the center of the screen, and

whatever back pressure takes place cause said oils to sweep the screensclean from the center of the point Where the stem 18 blocks the screen,the gas then flowing down the sides of the container, washing thesediment ofi the bottom toward the center and into the cup receptacle.

1 claim as my invention:

A liquid purifier comprising a cup-shaped casing having an inlet at thebottom and an outlet at the top, and upper and lower shoulders extendingaround the inside of the casing, upper and lower inverted cup-shapedscreens in said casing, the edges of said screens resting on saidshoulders respectively, and a cover on the casing having a dependin studwith its lower end extending through a hole in the upper screen andpressing upon the lower screen and a shoulder on the stud pressing uponthe upper screen, whereby said screens are expanded to close contactwith the shoulders.

In testimony whereoflI do afiix my signature in presence of twowitnesses.

ALFRED R. GI'FFIN.
